HosE-couPLING.

-To all whom t may concern.'

Be it known that we, HOWARD vania, have jointly invented certain new and usefulvlmprovements in Hose-Couplings, of

which the following is a specification.

The principal object of the presen-t inven-v tion is t'e supportthe recoilupset portion of the spirally wound metal coverrof the hose, produced by the action of the clamps upon git, in such a way that it continues to properly reinforce the rubber part of the hose but f without compressing it inward over 'the l which smaller end of the stem.A

The invention will be claimed at the end hereof but will be first described in connection with the embodiment of itchosen for illustration in the accompanying drawing in Figure 1', is an elevational View of a cou- -pling embodying features of the invention,

Fig. 2, is a longitudinal sectional view of the same, showing diagrammaticallyjand the stem`5, the smaller and free end of which 'perhaps in an exaggerated degree the posii tion ofthe metal covering in order to bring out graphically lthe mode of operation, and

Fig. 3, is a plan view of part of one of the clamps.

ln the drawings there is illustrated a hose of which 1, is the rubber partand 2, is A'the spiral metallic winding 'constituting a cover for the rubber part. 3, are clamps which are drawn and held together by screw-bolts ll, and operate to clamp the hose in respect to extends beyond the adjacent ends .of the clamps. There is nothing'new about the device as covered bythe immediately preceding detail description of it, but` the novelty will now be described. 6, isan enlarged annular open-ended Qchamber located at 'one end of the clamps and between them and-an intermediate portion 7, of the stem '5, and l the wall of which controls and supports the i Specicatbn of Letters Patent.

recoil-upsetting (shown at 8) of the spiral metal cover 2, and so holds thev latter up to the rubber part l, of the hose and not only contracting action between the clamps and stem, it being remembered that the rubber part 1, of the hose is compressible. In the absence of the chamber 6, this recoil-upsetting of spiral metallic winding would cause it to pull away from and no longer support the rubber part 1, of the hose, thus leaving the latter free to burst, and the re- -coil-upsetting would also reactupon the rubber part of the hose and compressit inward over the end 9, vof the stem, thereby weakening and probably cutting the rubber.

'l0 and 11, are groups of coperating -ngers-projecting from'the lateral edges of the clamps and they serve two purposes; rst, they prevent relative end movement of the clamps during assemblage and 'until the bolts 4, have been adjusted and tightened,

and second, they oppose bulging of any part of the hose between the meeting edges of the What'we'claim is: v A coupling for spirally wound metal covered rubber hose consisting essentially of4 clamps and a stem extending beyond the ends of the clamps, and said coupling provided with an enlarged annularv open-ended l chamber located'at one end of the clamps and between them and an intermediate por I vent undue compression of the rubber parto'f the hose over the endA of the stem, substantially as described.,
